Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi. My name is Krzysztof and I'm from Poland (Europe). I just got Ariens snow blower from my friend and after 2 hours of snow blowing machine stopped working. It was strange to me that muffler is red after few minutes and engine was not perfectly running but my friend said its normal. It was also weak for me, it went down every time I drove into 8inch of snow (not ice mountain ;) ). Today i checked spark plug, it was dirty but after cleaning it produces strong sparks. I turn round crankshaft couple of times and piston was not moving (i thing it should), i saw only one valve going up and down, i was unable to see other one cause spark plug hole is too small. When I try to start gas is going out from carburetor ( there is no air filter ?!?!?!) Please help me to identify Ariens model cause rear sticker is damaged.

Here's what I was able to read:
-engine Tecumseh
model # H70-130210D
ser 8305C
-front sticker
model# 7-10-m
serial# 26156
-rear sticker
model# 10M ?????
serial# 15192

Sorry for my poor english and thanks for any help.

OK. I will probably have parts within 2 weeks so I'll try to get gap meters to do it like book says :) Wish me luck because I need lots of it !

I zoomed in on the picture of the points. They look to have a lot of life left in them. Personally, I wouldn't touch them if you're getting strong spark. However, while you have them exposed, carefully spread the points and inspect the surfaces. if they're clean, check the gap and adjust if necessary. If they have corrosion or dirt on them, take a small piece of sandpaper, fold it over to have abrasives on both sides and clean the points surfaces. Then adjust if necessary. Points that are kept clean a dry can give very long service life especially in an engine used seasonally.

Where are the "points"?

which photo are they in?

im still trying to figure out exactly what the points are..

thanks, Scot

I cleaned almost all snowblower, for carb parts I will have ultrasonic cleaner . Now just have to wait long time for parts :(

  

Put a couple drops of light oil into the piece of felt that rubs against the cam lobe. It lubricates the cam surface/points actuator.

Borat - how can you tell from the photo the points are not pitted or weld distorted without seeing their surface?

         Well,  it was running when it blew up,   and lawnmower points only run one spark plug/ one cylinder....  Automotive points run 4, 6 or 8 cylinders (plugs on one set of contacts )-and run all the time..... Not just a hour here and there like yard stuff.    They get a lot less wear,  and when they fail,  they don't run (no room for misfire on a single cylinder)

   The points were working, OK.  When they fail they generally fail for good, OK.  What does that have to do with looking at points from the side side, not being able to see their surface and determining they “have a lot of life left in them”?  

 

    Points can operate fine while degrading.  They can run while slowly degrading from pitting, welding and carbon.  That the engine was running is no indicator of the condition of the points or future life.

 

    Changing under the flywheel points on an older Tecumseh engine is not like poping off the exposed distributor cap on a car engine.  On his old H70 the points are under the flywheel and head bolts have to be undone to get the cowling off along with the gas line.  Flywheels usually are stuck on pretty well and can be a pain to get off.  If the points were pitted or worn and working I’d change them along with the condenser to avoid going in there later but I would not know that unless their surface could be seen.

Friiy: Thank you for providing a good common sense reply on my behalf to Mr. Trouts query. Trouts: It would appear that you are trolling for another pi$$ing match. Not interested thank you.

AMEN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
